I have to refocus / re-collimate it anyway... I'm ripping a laser diode
out of a PlayStation3 laser sled and will probably be installing it in
an Aixiz heatsink. Should be a good bit of fun. Polymorph should be good
for making up the mounting bracket.
  Fortunately when I was assembly the CX
 scanner, I on;y had to make sure the beak was going in the right places... 
Indeed. The laser assembly on the SX and CX seems to be a 'blob' sitting
on one side of the scanner, with a fixed focus lens tied in.
   Getting down
to 0.08mm is going to be interesting, what with
 beam-scatter and fluorescence. And I really don't like the idea of using
 a focus-finder to set it up... viewing a laser through a magnifying lens
 seems like a really dumb idea to me, even with safety goggles. 
 'Do not look up this laser beam with your remaining eye' :-) 
 
Actually it's:
        WARNING
    BIG SCARY LASER
DO NOT LOOK INTO BEAM
   WITH REMAINING EYE
:)
  When I have a chance I;ll dig out what schematics I
have of the CX and SX
 enginers and get copies to you... 
No hurry. I've got a weekend of finishing assignment work ahead of me...
need to finish off my B.Sc project report, and one of my module
assignments. Fun!
